Sending Data to the Host Computer
Out of the box, the device supports two modes to send data to a host computer: via cable (RS-232 or USB); and
via Bluetooth (open/paired with an STB2078 cradle).

Cable Mode

Via cable (RS-232 or USB) the user interface indicates the active mode fo r transmitting bar code data to the host.
•
A displays on the screen when bar code data transmits via USB.
•
An displays on the screen when bar code data transmits via RS-232.

Bluetooth Mode

In Bluetooth mode (open or cradle), a Bluetooth icon displays on the screen when bar code data transmits via
Bluetooth.
The cradle receives data from the device via a wireless radio connection and tra nsmits it to the host computer via
the host cable. The device and cradle must be paired for successful wireless commun ication.
Pairing
Pairing registers a device to the cradle such that the device and c radle can exchange information. The cradles
operate in two modes: Point-to-Point and Multipoint-to-Point. In Point-to-Point mode, pair the device to the cradle
either by inserting it in the cradle (if pairing on insertion is enabled), or by s canning the pairing bar code. In
Multipoint-to-Point mode, you can pair up to seven devices to one cradle. To use this feature, scan the multipo int
bar code in Multipoint-to-Point Communication on page 4-19.
The cradle includes pairing bar codes on both its front and back. To pair the device with the cradle, scan a pairing
bar code. A high-low-high-low beep sequence followed by a low-high be ep sequence indicates successful pairing
and connection to the remote device. A long low, long high beep sequence indicates u nsuccessful pairing.
Lost Connection to Host
If scanned data does not transmit to the cradle's host, ensure that all cables are firmly inserted and the power
supply is connected to an appropriate AC outlet, if applicable. If scan ned data still does not transmit to the host,
reestablish a connection with the host:
1. Disconnect the power supply from the cradle.
2. Disconnect the host interface cable from the cradle.
3. Wait three seconds.
4. Reconnect the host interface cable to the cradle.
5. Reconnect the power supply to the cradle, if the host requires.
6. Reestablish pairing with the cradle by scanning the pairing bar code.
Radio Communications
The device can communicate with remote devices via Bluetooth Technology Profile Support, or by pairing with a
cradle. For radio communication parameters, detailed information abo ut operational modes, Bluetooth Technology
Profile Support and pairing, see Chapter 4, Radio Communications.
NOTE The pairing bar code that connects the device to a cradle is unique to each cradle.
Do not scan data or parameters until pairing completes.
